Some of my crested gecko eggs go to full development, and even pip. But the babies are dead. I have tried cut the egg carefully to help the baby but nothing. For some reason they're dead. I also get very healthy ones too. Incubated the same way, on moistend perilite at around 72-78 deg. I feed the parents mostly calcium dusted crickets, and sometimes apricot baby food.
Please help, thanks in advance Dave
